Secondly, categorizing enterprise versus business unit risks determines who can assume this risk for the organization. The organization should ask if the security risks are contained within one business unit and if the risks impact the entire enterprise or multiple business units.
Finally, organizations should document how disputed issues are escalated and resolved so that every business unit knows how and who needs to be involved in resolving risks. Documentation includes procedures to categorize the risk(s) and delegated authority levels by function.
A formal security risk assumption process that is documented and approved by the CEO and/or the Board of Director is a critical first step to successfully resolving contested risk tolerance issues. And importantly, the right people need to have the right level of authority to assume enterprise security risks for the organization.
Every successful CISO must determine and navigate the risk tolerance level of their respective organization -- as political as it can be -- but with the knowledge that risk tolerance drives organization values.
